I do endorse the nice suggestions given by Mr. Rajuprasad. It is good that you aspire to improve your knowledge, which is necessary for every professional. Our study does not end with our education in college. In college, we get only a few glimpses of the vast vista of knowledge. Our real study begins only when we come to face the stark realities of life. Learning has to be a continuous process. If we want to keep on living, we have to keep on learning. Also, knowledge is knowledge only when it is current. If we do not have updated knowledge, how can we claim to have knowledge on the domain we claim to be masters and experts.
One specific suggestion I will give you is to subscribe to one economic daily or a business magazine. Keep reading regularly. In a few years, you will be a rare expert on economics, business, management, and HR, wherever you go.
